I keep my coins on Ownr wallet and my partner knows all. And I have speciall things for passwords and so on
Someone asked, "What's the point of getting married to her if you don't trust her? Let's put trust aside. What we are talking about here is finance, and not just any kind of money; this is digital, where there is no name attached to a receiver's wallet unless the person makes it otherwise. So I would not advise you to share your entire wallet access with your wife (that's your decision, by the way, and I respect it), especially when you are still accumulating.
Instead, you can send a few of the coins or half of them to the wallet, where she can have control over them in an emergency. This is to avoid some kind of complications coming afterward in the family in cases of missing funds. If anything happens to the wallet out of the carelessness of either of you, you being the husband, who will you suspect first of moving the funds in the wallet? If we are to be realistic here, anyone who has access to our wallet that we are aware of becomes our number one suspect in cases of missing funds, no matter what relationships or connections we have with the person, unless the case is proven otherwise and the person in question is cleared of any guilt. So I will advise you to add a little security to the sharing of wallet access with your wife, as there are other better ways of doing it.
You present quite a bit of a dilemma Nwada001 because there can be a lot of variance in regards to the extent that couples might agree to having separate funds. or maybe the separate funds are known.. so there could be separate funds and joint funds, but then again, secrets can always be kept in regards to funds, so it could be a matter of degree how much secret is allowed (or even ends up happening) within any relationships.. whether spoken agreement or unspoken agreement... or if they are just lazy in respect to private matters of the other.
One possible way of dealing with a situation in which the partner wants to keep secrets, but also to share might be to have several different secret phrases on a Trezor, and the spouse may already be used to using the trezor and the secret phrases and also know the seed words for the back up, but that she might not realize that the secretive spouse has another wallet that can be accessed through the Trezor and then the secret spouse would pass that down upon his/her death by somehow making sure that the secret password is communicated after death, and that could even be in a sealed envelop in a lawyers office, but he lawyer would not be able to access the wallet without the seed or even known other aspects of the wallet.. so the information in the envelop might even say that this is ONLY intended for my wife after my death and the lawyer would not even be permitted to open it... but another aspect would be if the wife died simultaneously or before the instructions were corrected, then there should be a back up plan of some other heirs or otherwise maybe no one ends up being able to get access to those funds.
